Revert of Splitting of layers for correct intersections

Revert of Splitting of layers for correct intersections (patchset #17 id:310001 of https://codereview.chromium.org/595593002/)

Reason for revert:
Static initializers count increased

Original issue's description:
> Splitting of layers for correct intersections
>
> Sorting 3d-sorted layers and rendering them in that order causes issues
> when layers intersect. Instead place 3d-sorted layers in a bsp tree and
> fragment any intersecting layers into non-rectangular quads. We can then
> render the fragments in the correct sorted order regardless of
> intersections.
